This invention relates to building construction and particularly pertains to a method and means of forming walls.

In the construction of buildings it is common practice to provide a back wall and to apply an outer wall thereto and in fixed relation therewith. The outer wall usually incorporates reinforcing elements which are imbedded within the cementitious mixture of the inner wall.

This provides a reinforced Wall section applied to a relatively rigid backing. Such a construction has been found to be especially desirable in sections of the country where earthquakes occur, since the wall structure affords some flexibility while remaining stable. Structures of this type are also desirable where it is necessary to remodel or repair building structures. In forming wall structures of this type it is necessary to provide means for rapidly and accurately determining wall thicknesses since in most instances the cementitious material is applied to the backing by pressure gun apparatus which applies the cement mix in a finely divided hydrated state until a sufiicient thickness of the material has accumulated on the packing to provide a desired wall structure. Heretofore guide means have been used which are subject to tension and are liable to become dislodged, or disarranged, during the time the cementitious material is being applied. It is the principal object of the present invention therefore to provide means whereby the thickness of. the wall may be determined readily and whereby the guide means may be accurately and rigidly supported during the entire Wall construction operation, and may be thereafter easily removed.

The present invention contemplates the provision of supporting members applied to the wall reinforcing elements and carrying guide members by which the thickness of cementitious material may be determined and maintained.

The invention is illustrated by way of example in the accompanying drawing in which:

Figure 1 is a view inelevation indicating the application of the present invention to the reinforcing elements of the wall structure.

Fig. 2 is a view in horizontal section through the wall structure as seen on the line 2-2 of Fig. 1 and discloses in detail the construction with which the present invention is concerned.

Fig. 3 is an enlarged fragmentary view showing an end of a supporting bracket as seen on the line 3-3 of Fig. 1.

Fig. 4 is an enlarged fragmentary view in.

elevation showing the manner in which a supporting bracket receives a guide element.

Referring more particularly to the drawing, Hi indicates a backing wall. This wall may be of any desired construction, and may be of frame, masonry, or cement. Disposed in a plane. parallel to) the surface of the wall it and suitably spaced therefrom is a reinforcing structure, such, for example, as the horizontally extending reinforcing rods H and the vertically extending reinforcing rods l2. These rods are'tied together in any commonly accepted manner and are spaced from the face of the wall to provide an intermediate space l3. Applied to the rods H and I2 at intervals throughout their lengths are ground wire brackets i4. These have straight portions l5 which extend longitudinally of a reinforcing element and are preferably fastened thereto by wires I6 and I1. At one end of the straight portions an outwardly extending arm [8 occurs. This arm is formed as a continuation of the straight portion of the bracket and terminates in a curved end H! as indicated in Fig. 3 of the drawing. A serration is cut across the top face of the curved end 9 to form a V-shaped seat 20 and a serration is formed upon the diametrically opposite side of the bracket to form a V-shaped groove 2| of relatively smaller size. The V-shaped seat 20 receives a transversely extending ground wire 22 which is stretched across a plurality of the ground wire brackets and seats concentrically in the V-shaped seats 20 of these brackets. The opposite ends of the ground wires 22 are secured around the shank of anchor nails 23 which when driven into the backing wall Ill Will draw the ground wires tightly across the free ends of the brackets. Attention is directed to the fact that the extensions N3 of each of the ground brackets may be sufficiently flexed to produce any desired spacing of the ground wires with relation to the plane of the reinforcing members II and I2 and the back wall It]. In this manner it is possible to insure that when the reinforcing members II and I2 are in fixed relation to the back wall [0, the application of the brackets to the reinforcing members and the adjustment of the brackets will make it possible for the thickness of the wall to be readily forcing bars I l and I2 are suitably spaced from the face of the backing wall l0, after which the ground wire brackets M are secured at intervals as the dictates of the mechanic may determine. The brackets may be applied to both reinforcing elements II and reinforcing elements I2 in which event ground wires 22 may be strung vertically and horizontally and ,fastened to the nails 23. The extension portions l8 may be bent as desired, after which the nails may be driven into the wall ID, to create any desired degree of tension on the ground wires 22. cementitious material may be applied to the backing wall It until it has accumulated on the backing wall to the level indicated by the dotted line 25 in Fig. 2 of the drawing. When the cementitious material has accumulated to this level, a wall section 26 will be formed on the face of the wall section if), said section being of uniform thickness and reinforced. The ground wires 22 may then be taken away so that any desired surface can be thereafter applied to the outer face of the wall portion 26.

It will thus be seen that by the method here described and the structure here shown that a reinforced wall structure may be readily set up and a reinforced Wall of a desired thickness accurately applied.

While I have shown the preferred form .of my invention as now known to me, it will be understood that various changes might be made in the combination, construction, and arrangement of parts by those skilled in the art, with-- out departing from the spirit of the invention as claimed. 7

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. Means for gauging the thickness of a wall to be made by the accumulation of cementitious material against a backing and around reinforcing elements, said means comprising brackets secured to said reinforcing elements, the outer ends of said brackets terminating in a plane parallel to that of the reinforcing elements and spaced therefrom, guide wires rigidly secured at their opposite ends and stretched across said brackets to be held thereby in spaced relation to the reinforcing elements whereby when the cementitious material has accumulated on the backing to a plane coincident with the guide wires the desired wall thickness will be made.

2. Means for gauging the thickness of a wall to be made by the accumulation of cementitious material against a backing and around reinforce ing elements, said means including a bracket having a shank adapted to be fastened to a wall element, an outwardly extending portion at one end of said shank adapted to be set with its outer end in a desired offset relation to the plane of the shank, and a ground wire adapted to be strung across the end of said bracket to When this has been accomplished,

be held in spaced relation to the plane of the shank of the bracket.

3. Means for gauging the thickness of a wall to be made by the accumulation of cementitious material against a backing and around reinforc ing elements, said means including a bracket having a shank adapted to be fastened to a wall element, an outwardly extending portion at one end of said shank adapted to be set with its outer end in a desired offset relation to the plane of the shank, and a ground wire adapted to be strung across the end of said bracket to be held in spaced relation to the plane of the shank of the bracket, said freev end of the bracket being formed with a seat across which the ground wire lies.

4. Means for gauging the thickness of a wall to be formed'by the accumulation of cementitious material against a false frame and around reinforcing elements, said means comprising'reinforcing elements erected in spaced relation to the false frame, brackets secured to the reinforcing elements, the outer ends of said bracketsv terminating in aplane parallel to the reinforcing element and spaced therefrom, guide wires secured at their opposite ends and stretched across said brackets to be held thereby in spaced relation thereto, whereby when thev cementitious material has accumulated onj the false frame to a plane parallel to the, guide wires the Wall will have attained the desired uniform thickness.
